The study found that Jehovah's Witness patients experienced similar or even better short- and long-term survival than non-Jehovah's Witnesses. Specifically, propensity-matched comparisons between Jehovah’s Witnesses and patients who received blood transfusions showed "fewer postoperative myocardial infarctions, fewer episodes of postoperative ventilator support beyond 24 hours, fewer additional operations for bleeding, shorter intensive care unit and postoperative lengths of stay, and a lower hazard for in-hospital death" among Jehovah's Witnesses.

Overall the study authors conclude that "current extreme blood management strategies do not appear to place patients at heightened risk for reduced
long-term survival." However, they note that future analyses may consider looking at which specific care-management strategies contribute to these outcomes.
